I opened up the 400 I purchased for the Incognito upgrade and it had a 48k upgrade already added. The upgrade was made by Intec Peripheral Corp. Posting the images, may be of use in development of Incognito.

 

These are mods made to bottom of main board to support the additional memory.

That is a really clean upgrade! :D And good pictures. Thanks for that.

 

As for the Incogneto 400, really really tempting. I'll keep an eye on this thread.

Incognito 800 and 400 would be two different cards. The Incognito 800, had three production runs. Run 3 is in its final stages. Incognito 400 is still being developed by Candle, it is in a holding pattern until current projects and life permit the time for them to be completed. The Incognito 400, should have similar specs to the Incognito 800 listed below.

 

The Incognito 800 gives you the following:

1) 4 slots for OS separate for Colleen and XL/XE mode.

2) 64k of FLASH for future GUI
3) 2 slots for BASIC/CARTRIDGE (FLASHABLE)
4) Built in, configurable PBI CF card storage (works as PBI in XL/XE mode, and through SDX driver in Colleen mode)
5) Built in FAT32 loader (SIDE)
6) Built in Sparta Dos X (FLASHABLE)
7) Onboard Real Time Clock
8) 1MB Axlon compatible memory expansion for Colleen mode
9) 64k/320k/576/1088k total memory available in XL/XE mode
10 Up to 52k of memory in Colleen mode (configurable)

 

Best Regads

The last few days I have been modding and testing my Pal 400.

 

It works (almost) great now, although I have one problem.

 

AtariMax 8Mbit carts do not work properly.

 

Thanks to another thread here on AtariAge I found out that in the 400 pin S of the Cartport does not have Ph2 (which is what the docs say, but it's wrong).

So I changed that, and that was a nice fix (before the Fix I also had issues with other modern carts).

 

But the AtariMax 8Mbit carts give a lot of issues with a lot of titles (which are compatible with the 400 btw). On my 800: no problems at all.

 

The 400 has 48K ... I'm wondering whether someone has a clue what can be wrong here.

HELLO TO YOU ALL !

 

I need to know if my Atari 400 has 48K or 64K or 52K memory upgrade ??? Because I tested 1 program called SysInfo. Not sure which version is that. On the main screen, it say "65536" bytes and I clicked on memory menu on the top and it stated "52K" on the same program ! So I need to know WHICH programs to download and testing properly without any confusing. Thank you to all !

I haven't seen Candle back in on this topic in a while. I wonder what progress if any he has made on this and if it is still a go. All of our wishing could be nothing but HOT AIR. I for one want it to happen but I'm not going to push him to it. Lets see if he will respond or if we need to PM him.

Stumbled across this older thread doing a web search. God I would love one or two of these if they are ever made. I'm probably in the minority here but I think the 400 is just awesome. Probably because it was my first computer. Even back in the day I thought I'd want it over the Atari 800. I thought the 800 looked more like a typewriter, the 400 just looked more futuristic. Not that I had the money for an 800. I didn't even mind the keyboard back in the day. I do have an Incognito 800 now though. I actually got my 13 year old son an Atari 400 for Christmas and he loves the way it looks on his desk. He frequently jumps on it with friends for some quick gaming. They are intrigued by it. He's always very impressed by that solid block of metal you see when you open the cartridge door. (I was too:). Unfortunately it can't play all the latest software releases, which would impress his friends. My son points out that it's 1979 tech!  Something about the Atari 400 being able to run the best stuff would be so cool and make it more useful as such a great game machine. Put me down for 2 if they are ever made! :)

I love my 400s. It was my first Atari and still my favourite. I love the look of it, especially the keyboard.

I have added the @tf_hh sccc video mod board and RAM upgrade so can use it to play most of the back catalogue.

@candle still has the 400 I loaned him many years ago to develop the 400 incognito and it's still on his to do list. So we can live in hope

schematics for incognito-lite as this is codenamed have been sittin on my disk for about 8 years right now. they need massive lifting before i could start with pcb design, and i need to refresh my memory on how this suppose to work. the biggest issue ther is that every expansion card 400 has is internal, and this is a problem for sd card access. i know ribbon cables with sd slots exist, but this is good for low speed interfaces - if any of you have some ideas on how to go about this, im open for discussion

I don’t know how strong the 400 shielding will be, but maybe a concept using WiFi SD cards is a way to go.

In that context have a look at that project: https://github.com/ardyesp/ESPWebDAV

Maybe an external antenna could be connected.

Maybe a really cut down version just giving ram upgrade and selectable OS? Then let some other device like sio2xx or AVG cart etc do the file shifting? My guess is that the 400 will be used as a games machine rather than anything heavy duty .

Just my 2ç
